Seal cover used for biological reaction

Abstract

The invention relates to a seal cover used for biological reaction. The seal cover comprises a reaction zone and a liquid adding zone; the reaction zone comprises a reaction zone top wall, a reactionzone side wall, and a reaction zone back wall; the reaction zone top is provided with a recess close to the reaction zone back wall; the front end of the reaction zone is connected with the liquid adding zone through a flow guide device; in reaction, a reaction chamber is formed via matching of the reaction zone top wall, the reaction zone side wall, the reaction zone back wall, and a slide; the reaction zone side wall, the reaction zone back wall, and the slide are designed to match each other in a sealed manner; and a liquid enrichment zone is formed at the recess. The seal cover is capableof reducing influences of reaction liquid evaporation and bubble generation on experiment results in thermal remediation process; the seal cover is helpful in spreading of reaction liquid, and entering of reaction liquid into the reaction zone smoothly and rapidly; and the seal cover is helpful in circulation of heat energy in reaction liquid, and heat energy uniformity is ensured.

Description

technical field [0001] The invention relates to a biological experiment device, in particular to a sealing cover for biological reactions. Background technique [0002] In biological experiments, the samples are pre-treated, and then undergo a series of staining and other treatments, so that the experimenter can clearly observe the conditions of the samples. The usual treatment includes a series of steps such as pretreatment and staining. Normally, manual operation is used to place the sample tissue on the slide, and go through steps such as dewaxing, repairing, staining and dehydration. The above steps need to remove the coverslip from the slide. Take it off the top of the slide to add liquid, and then put the cover slip back on. This process is time-consuming and requires manual monitoring, so there are coverslips that can be applied to tissue processing by automated means. This type of cover slip can be applied to automatic implementation. Both the front end and the bac...

This process is time-consuming and requires manual monitoring, so there are coverslips that can be applied to tissue processing by automated means

This type of cover slip can be applied to automatic implementation. Both the front end and the back end of the cover slip are connected with the outside world, so that the reaction liquid can flow into the reaction area from the front end of the cover slip and flow out from the rear end of the reaction area, realizing liquid addition, cleaning and The automatic completion of liquid drainage, etc., but this kind of cover slip has the problem of air bubbles and cavities during thermal repair. This is because the thermal repair process is long and the temperature needs to reach 100 ° C, which exists between the slide and the cover slip Bubbles and evaporation will occur in the reaction liquid, and the addition of new reaction liquid during the heat repair process will affect the overall temperature of the heat repair. When heating, heat will be lost from both ends, resulting in heat loss and uneven heating
